STOVE OR FURNACE.

SPEdIFICATION forming part of Letters Patent No. 687,549, dated November26, 1901.

Application filed December 31, 1900. Serial No. 41,615. (No model.)

To all whom it may concern:

Be it known that I, JAMES WILSON, of the city of St. Louis,.State ofMissouri, have invented certain new and useful Improvements in Stoves orFurnaces, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, forming apart hereof.

This invention relates to stoves or furnaces; and it consists of thenovel construction, combination, and arrangement of parts here inaftershown, described, and claimed.

The object of this invention is to'provide an improved stove or furnacehaving means for creating either an up or down draft.

Another object is to provide a stove or furnace constructed so that thefire can be started below the fuel by means of an updraft and after thefuel has become ignited it can be inverted within the fire-pot, placingthe fire above the fuel, and a downdraft created, thereby consuming amaximum portion of the gases and radiating greater heat with a smallamount of fuel than is given by an ordinary stove using a larger amountof fuel.

Another object is to provide a reversible fire-pot which may be operatedafter the fire has been started to overturn the fuel contained therein,bringing the fire to the top, so that the flames will pass through thefuel when the downdraft is created.

Figure 1 is a vertical sectional view of my improved stove, taken on theline 0 c of Fig. 3. Fig. 2 is a vertical sectional view taken on theline at d of Fig. 4 substantially at right angles to that shown inFig. 1. Fig. 3 is a horizontal sectional view taken on the line a a ofFig. 1, and Fig. 4 is a horizontal sectional view taken on the line b bof Fig. 2.

Referring to the drawings in detail, 1 indicates the wall of the stove,leading through which are two openings 2, one of them near the top-ofthe stove and the other near the bottom. The pipe or flue 3 is rigidwith the wall of the stove for receiving the products of combustion fromthe openings 2 and conveying them to any suitable outlet. Rigid with thewall 1 of the stove, a suitable distance above the bottom, is aninterior flange 4, extending entirely around the inner side of the stoveand supporting the grate 5. The said grate 5 is arranged in the form ofa bowl the stove, one of said trunnions projecting outwardly and adaptedto receive a crank 9, whereby it can be inverted whenever it is desiredto create a downdraft within the stove. The said fire-pot is providedwith short-projections 10, which operate between the bars of the grate 5and assist in guiding the firepot around into the required positionwhenever it is operated by the crank 9. v

The stove is provided with a door 11, leading from which is a chute 12,which extends downwardly within the stove and terminates above thefire-pot 7. The purpose of the chute 12 is to receive and guide the fuelinto the firepot. Leading from near the top of the stove is adraft-passage 13, which extends downwardly and has its lower end bentinwardly above the fire-pot in order to guide the draft so that it willpass through the fire. The said draft-passage is provided with aslide-damper 14, whereby it may be closed whenever it is desired to usethe updraft or to cutoff the supply of air from the interior of thestove. It will be noticed that the draft-passage 13 is located at theside of the stove and has its lower end extended out near the center ofthe stove and terminating directly above the firepot. This arrangementleaves a freer space for the updraft and does not interfere with thepassage of the smoke to the upper outlet when the updraft is used.

The stove is provided with the usual ashpit, having an ordinary door 15,provided with openings and a slide-damper, whereby the passage of air ordraft may be admitted or cut off, as required. Above the ash-pit is aguide 16 for receiving and guiding the ashes into the ash-pit. I

17 indicates a valve for closing the opening 2 at the top of the stove,and 18 denotes a damper for closing the pipe 2 at the bottom.

In using my improved stove or furnace the fire is started within thefire-pot by means of an updraft, the air passing through the ashpit andupwardly through the fire-pot and fuel and the products of combustionpassing out through the opening 2 adjacent to the top of the stove, thevalve 17 being left open to permit the passage. The valve 14 is closedto shut out the air from the draft-passage 13 until the fuel becomesthoroughly ignited, after which the openings through the door 15 areclosed and the valve14 is moved to admit the air into the draft-passage13. The valve-17 is moved to close the opening 2, and the damper 18 isopened to allow the draft to pass out through the outlet. The crank 9 isthen turned to reverse the fire-pot 7, which, as above stated, ispivotally supported within thegrate, which operation brings the fireabove the fuel and causes the flames to pass through the fuel as theairis admitted through the downdraft-passage 13. The flange 14 proventsany of thegases from passing around and above the fire-pot, so that amaximum portion thereof will be consumed by the flames which passdownwardly through the fuel. This results in greater heat being radiatedfrom asmall amount of fuel than can be generated by an ordinary stoveusing a larger amount of fuel.

The stove is simple in construction, easily operated, and is devoid ofall useless appurtenances'.

I claim- '1. A stove having a grate in the form of a bowl, a reversiblefire-pot, supported within the grate,.a draft-passage leading from thetop atone side of the stove. and terminating near the center ofthe'stove above the fire- .pot, a pipe 3 atone side of the stove,-openair and smoke through the pipe, and. means for turning the fire-potas required when an assi n;

up or down draft is used, substantially as specified.

2. In a stove, a grate in the form of a bowl, a fire-pot locatedtherein, a downdraft-passage leading from the top of the stove at oneside thereof and terminating near the center of the stove above thefire'pot, a pipe at one side of the stove, an opening leading into thepipe below the fire-pot to be used as a passage for the smoke when adowndraft is ad'- mitted, a damper for controlling the passage of thesmoke and air through the pipe, a second opening above the fire-pot tobe used as a passage for the smoke when an updraft is admitted, and adamper for controlling the passage of the smoke and air through the saidopening, substantially as specified.

3. A stove having a grate in the form of a bowl, a fire-pot locatedabove the grate, a fuel-passage leading from the feed-door'andcommunicating with the fire-pot, a downdraftpassage leading from the topat one side of the" stove and terminating near the. center thereof abovethe fire-pot, a flue at one side of the stove, anopening leading intothe flue below the fire-pot to be used-as a passage for the smoke when adowndraft is admitted, a damper for controlling the passage of the smokeand air through the pipe adjacent. to the said opening, a second openingabove the fire-pot to be used as a passage for the smoke when an updraftis admitted', a damper for controlling the passage of the smoke and airthrough the said opening, and means for rotating'the fire-pot asrequired when an up or down draft is admitted, substantially as Intestimony whereof I'afli x my signature in presence of two witnesses.ings leading from the stove into the said pipe, dampers for controllingthe passage of the JAMES WILSON.- W itnesses:
